The Prince and Princess of Wales appeared to share a tender moment as they supported King Charles at the Scottish Coronation today.
The pair joined the monarch and Queen Camilla at St Giles Cathedral in Edinburgh where the King was presented with the Honours of Scotland – the country's crown jewels – during a service of thanksgiving and dedication at St Giles' Cathedral.
Kate looked stunning in a Catherine Walker coat dress she's worn several times - including at Easter this year, an intricate Philip Treacy hat and a necklace from the late Queen's collection. William wore his RAF No.1 Uniform with his Order of the Thistle mantle.
They took part in the procession into and out of the cathedral and sat alongside Charles and Camilla as they enjoyed the rousing musical performances and readings.
And pictures taken during the service show Kate placing a tender hand on William's back as they exchanged a few words, while others show them smiling at each other.
Meanwhile after the ceremony and during the RAF flypast over the Palace of Holyroodhouse, Kate could also be seen giving her husband a cheeky bum pat, body language expert Judi James told the Mirror.
It comes as the couple were referred to by their new little-known titles during the service, the Duke and Duchess of Rothesay.
William and Kate have more than one royal title with the pair inheriting a raft of new ones on the accession of King Charles last year - with many of them little known.
The title Duke of Rothesay is always reserved for the heir to the throne along with the other Scottish styles - Earl of Carrick, Baron of Renfrew, Lord of the Isles and Prince and Great Steward of Scotland.
This means the heir's wife Kate is also known as Countess of Carrick, Baroness of Renfrew and Lady of the Isles. However, William and Kate will mainly use Duke and Duchess of Rothesay - as this title is higher in rank.
The service at the cathedral featured centuries-old aspects of Scottish royal tradition along with new additions such as pieces of music written specially for the occasion, a psalm sung in Gaelic and the use of passages from the New Testament in Scots.
The Moderator of the General Assembly of the Church of Scotland, Rt Rev Sally Foster-Fulton, preached the sermon and then provided a blessing to close the service.
During the ceremony, the sceptre and crown from the Honours of Scotland were presented to the King, along with the Elizabeth Sword.
This is a new sword specially crafted to be used in place of the current Sword of State, gifted to James IV by Pope Julius in 1507, which can no longer be used due to its fragile condition.
